WHAT IT DOES

What props_get_thumbnail does on Propresenter

AI agents call props_get_thumbnail to retrieve information from Propresenter without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why props_get_thumbnail is rated Low

This tool retrieves a thumbnail image for a prop in ProPresenter 7. It performs a read-only query operation with no side effects, data modification, or external triggering. The worst-case misuse would be unauthorized access to presentation thumbnails, which has minimal blast radius.

From the tool's definition Tool name contains 'get' and description states 'Get thumbnail for a specific prop' - both indicate retrieval without modification.

Attacks that exploit this kind of access
